D-Link Gigabit SFP Transceivers plug into Gigabit and Fast Ethernet switches via their
GBIC slots. They allow for the expansion of Gigabit Ethernet networks by providing high
speed connections over a fiber-optic or twisted-pair cable. The fiber-optic transceivers
have standard duplex LC connectors to provide maximum compatibility. They are hot
pluggable and Small Form Factor Pluggable (SFP) compliant with the Multi-Source
Agreement (MSA) specification.

Small Form Pluggable (SFP) Package
The Gigabit SFP/Ethernet Transceivers use the Small Form-factor Pluggable (SFP) design.
They provide the necessary signal amplification for data to be transmitted to the network
cable from the port, and vice versa. The SFP form factor is advantageous because it is
smaller than other form factors such as Xenpak, X2, and 10G XFP, ensuring lower costs,
lower power disruption, and higher port density.

Multiple Applications
Applications of the DEM-300 Series fiber transceivers include distributed multi
processing, Gigabit switch cascading, high-speed I/O file transfer, bus extension
application, and channel extender/data storage. This versatility is invaluable for an
expanding network, and helps the infrastructure grow with the business.

Hot Pluggable
All D-Link transceivers are hot pluggable. You can connect a transceiver while the system
is powered on without causing any issues, and easily swap one for another without having
to reboot the switch each time. This permits modules to be added or removed without
interrupting the network, facilitating maintenance and greatly reducing downtime.
